Unfortunately had a faulty unit
Unfortunately received one that had some form of issue, the motor vibrated and didn't move how it should, the controller Im using is fine as I reordered another nema from Amazon and that one worked perfectly

Quality product
Great product. I've conducted multiple tests with these steppers and they work well with the motor drivers I purchased and have some very long cables which will be immensely useful for my project. These arrived in a well packaged box and will purchase from here again when I need more.

My printer is now 3 times faster with 5000 m/s2
The media could not be loaded. Incredible, I replaced the X and Y motors of my Ender 3 Pro with 42-40 ones of this and I was able to increase the acceleration from the default 500 m/s2 to 5000 mm/s2, and probably can go higher with a little more voltage, but I'm quite happy with the current speed, with the input shaper and the linear advance features of Marlin, now the printer prints 2.5-3 times faster with higher quality. Though the top speed is still limited with 120 m/s as the hot end can only melt around 12-12.5 mm3/s of filament. The model in the video normally prints in 12-13 hours, I was able to complete it in 5 hours, unbelievable... I increased the default voltage from 580 mV to 850 mV and that's it. The original motors, especially the X motor was getting too hot, around 50 °C, even with an acceleration of 1000 m/s2 and the aforementioned 580 mV input voltage. The new ones never go over 30 °C. I'm super happy and planning to buy another 5 of these to replace the Z axis and my MMU2s motors. Oh, I didn't need to change my printer cables, these were a drop-in replacement, my board is an SKR 3 EZ.

Powerful motors
Bought these to use with a 4:1 pulley for some moderately heavy Venetian blinds. Only gripe is that without idle hold enabled, then still turn when under load.

Very quite Steppers
I was surprised by how quite these stepper were using a4988 motor drivers they don't sing like my other steppers.

Don't be fooled. These are not 1.5A
These are not 1.5A. They trip out at anything over 600mA
